## What it is
Craft is a simple Minecraft clone written in a few thousand lines of C using modern OpenGL shaders, with terrain generation via simplex noise and world persistence in SQLite. It supports online multiplayer through a Python-based server and runs on Windows, macOS, and Linux.

## Use cases
- play a lightweight minecraft-like voxel game on desktop
- learn how to write a voxel game engine in C with OpenGL
- use a minimal codebase as a starting point for building a custom block game
- self-host a multiplayer voxel world server
- study terrain generation with simplex noise and shader-based rendering

## When to choose
- you want a small, readable C codebase demonstrating OpenGL voxel rendering
- you need a lightweight minecraft-style game that runs on modest hardware
- you want a foundation to fork into your own voxel game
- you want to self-host a simple multiplayer block-building server

## When to avoid
- you want a full-featured modern Minecraft alternative with mods and active development
- you need a production game engine or extensive tooling
- you prefer working in a higher-level language or a maintained engine like Godot or Unity

## Facets
- artifact type: application
- maturity: maintenance
- function: game-engine, graphics, simulation
- domain: graphics, gaming-tools
- platform: windows, cpp, python, cross-platform
